How do I adjust my microphone volume?

Check Your Operating System’s Sound Settings

The operating system’s sound settings panel allows you to control the microphone volume at a system level. Here’s how to locate and adjust the mic volume in some common operating systems:

On Windows 10 and 11, open the Start menu and go to Settings > System > Sound. In the Sound settings, select the microphone you want to adjust under the Input section. Use the volume slider to raise or lower the volume.

On Mac OS, open System Preferences > Sound. Go to the Input tab and select your microphone. Use the Input Volume slider to adjust the mic volume.

On ChromeOS, click the status area in the bottom-right corner and select Sounds. Under the Input section, select your microphone and use the volume slider to adjust the mic level.

The operating system’s microphone settings affect the volume globally, so changing it from the sound control panel will adjust the mic volume for any application using the microphone. Raising the volume here can help if your mic volume is too quiet across different programs.

Check Your Microphone’s Physical Volume Control

Many microphones have a physical volume control knob or dial built directly into the device. Before adjusting the volume digitally in your computer or recording software, take a look at your microphone to see if it has its own physical volume control.

Examine your microphone closely for a dial or knob labeled “volume.” This may be located near the top, bottom, or back of the device. If you find the volume control knob, try adjusting the microphone’s volume directly by turning the dial.

Turn the knob clockwise to increase the volume level. As you turn the knob clockwise, speak or make sound into the microphone to test the volume increase. Turn the knob counter-clockwise to decrease the volume level.

Adjusting your microphone’s physical volume knob can help boost or reduce the volume being sent to your computer before it reaches your recording software. This analog volume control gives you another way to fine tune your microphone volume before using digital controls.

Adjust Volume in Your Recording/Broadcast Software

One of the easiest ways to adjust your microphone volume is directly within your recording or broadcasting software. Most programs like Audacity, OBS, Adobe Audition, etc. will have controls to adjust the input volume from your microphone.

To adjust the volume, first open your recording or broadcasting software. Look for a microphone or input volume slider, which is often located near the main audio controls. In Audacity for example, you’ll see a microphone volume slider in the top toolbar. Drag this slider left or right to lower or raise the volume to your desired level.

Monitoring your microphone input as you adjust the volume will help you find the perfect sweet spot. Make smaller incremental adjustments to hone in on the right volume. Things to listen for are distortion at high volumes or your voice being too quiet at low volumes.

Adjusting the mic gain directly in your recording/broadcasting software is usually the quickest and easiest way to control volume. Just be aware that boosting the volume too high can lead to clipping or distorted audio.

Use Keyboard Shortcuts

One convenient way to adjust your microphone volume is by using keyboard shortcuts. This allows you to quickly raise or lower the volume without having to navigate through settings menus.

On Windows, you can raise your microphone volume by holding Ctrl and pressing the Up arrow key. To lower the volume, hold Ctrl and press the Down arrow key. This will incrementally increase or decrease the volume level.[1]

On Mac, you can raise the microphone volume by holding Cmd and pressing the Up arrow key. To lower the volume, hold Cmd and press the Down arrow key. Like on Windows, this will gradually adjust the volume up or down.[2]

Using these handy keyboard shortcuts makes it quick and easy to get your microphone volume to the right level without having to go through menus or settings.

Check Cable Connections

One of the most common issues causing low microphone volume is a loose cable connection. First, ensure the microphone cable is fully inserted into the computer’s USB or audio input port. Loose connections can prevent the microphone from receiving enough power and result in low volume recordings. If the cable is not fully plugged in, unplug it and reinsert firmly until it clicks into place.

You can also try connecting the microphone to a different USB or audio input port on your computer. Some ports may be damaged or not functioning properly, causing connectivity issues. Switch to an alternate port as a quick way to test if the problem is with the specific input.

Finally, inspect your microphone cable for any damage or loose connectors. Frayed cords or bent plugs can obstruct the signal path and lead to low volume issues. If the cable appears damaged in any way, it’s best to replace it with a new one. High quality cables with secure connections will provide consistent performance. Reputable brands like Blue or Audio-Technica often sell replacement cables for their microphones.

Update Microphone Drivers

One way to adjust your microphone volume is by updating its drivers. Microphone drivers act as the software that allow your operating system to properly communicate with the microphone hardware. Keeping these drivers up-to-date can resolve issues like low volume or static sounds.

To update your microphone drivers, first identify the brand and model of your microphone. You can usually find this information printed on the device or in the manual. Once you know the make and model, visit the company’s website and search for the latest drivers available for download.

Be sure to only download drivers directly from the official manufacturer to avoid potentially installing malware. Carefully follow the installation instructions, which usually involve running an exe file and restarting your computer. This will install the new drivers and replace the old ones. After restarting, your operating system should fully detect the microphone again with the updated drivers.

Updating drivers is an easy process that can often fix mic issues caused by software conflicts. Just be sure to get drivers directly from the source company to ensure compatibility and security.

Adjust Microphone Gain

The microphone gain controls how much of the incoming audio signal is amplified before being recorded. Increasing the gain boosts the microphone’s sensitivity and makes quiet sounds louder. Decreasing the gain lowers the sensitivity so loud sounds don’t get distorted. Microphone gain is different from volume, which controls the playback level.

To adjust microphone gain:

  • Locate the gain control in your operating system’s sound settings window or audio recording/streaming software. There may be a slider or options like +dB and -dB.
  • Speak into the mic at the same loudness you expect to use while recording/broadcasting. Watch the input level meter move.
  • Increase the gain until the loudest peaks hit around 75% on the meter. This leaves headroom before distortion occurs.
  • If the audio is peaking/distorting during loud parts, reduce the gain.

Setting the right gain level improves sound quality by maximizing the signal without allowing clipping. Boosting a weak signal is better than turning up volume later. Proper gain structure from mic to speakers makes the most of your equipment’s capabilities.

Use a Microphone Amplifier

If your microphone volume is still too low even when the microphone gain is maxed out in your computer’s sound settings or recording software, you can use an external microphone amplifier. A microphone amplifier is a hardware device that boosts the signal from your microphone before it reaches your computer.

A microphone amplifier serves as a pre-amp, increasing the strength of the mic’s signal so you don’t have to boost it as much digitally via software. This preserves sound quality by allowing you to record at optimal gain levels.

Look for a microphone amplifier that offers plenty of clean gain for your needs, along with XLR and 1/4” inputs to connect your mic. Some amplifiers also provide phantom power. Popular options include the Cloudlifter CL-1, the Fethead by Triton Audio, and the sE Dynamite.

After connecting your microphone to the amplifier, connect it to your audio interface or computer input. Start a test recording and adjust the amp’s gain knob until you reach your target recording volume before making fine adjustments in software.

Consider a New Microphone

If your microphone volume is difficult to control or maxed out, investing in a higher quality microphone may provide more optimal results. More professional-grade mics often have built-in gain control, selectable pickup patterns, and extended dynamic range for greater flexibility. There are also differences in sensitivity and loudness between condenser and dynamic microphones to consider. Condenser mics tend to be more sensitive and capture high volumes and subtleties more easily. Dynamic mics typically have lower sensitivity/output but allow for more stability in super-loud environments like live performing. Research microphone types like large vs small diaphragm, cardiod vs omni-directional, etc. to choose the right mic characteristics for your needs and room acoustics.

Set Up Compressor/Limiter Filter

To further control your microphone volume, you can set up a compressor or limiter filter to automatically manipulate the audio. A compressor evens out the volume of your mic – it reduces loud peaks by attenuating the signal, and then boosts quiet sounds by increasing the gain, resulting in a more even sound.

As this article explains, “A compressor is used for shaping dynamic range of a signal by attenuating the loud parts and boosting the quiet parts.”

On the other hand, a limiter prevents your mic’s output from distorting by restricting the upper volume limit. As loud noises approach that threshold, the limiter activates to push the volume down. As noted in this resource, “Limiters turn down the volume of a sound more strongly. This is because they use a higher ratio than compressors.”

So while a compressor smooths out variations in volume to achieve consistency, a limiter guards against sudden spikes that could cause distortion. Utilizing one or both can give you more precise control over your microphone’s levels.
